The powerful, compact personal air cooler pulls warm air from the room through its evaporative water filter to fill any space with cool, clean comfortable air! Simply fill it with water, plug it into any standard wall outlet or USB port and enjoy! It runs up to 10 hours per fill at 1 level of mist! The whisper-quiet fan and soothing night light make it perfect to use throughout the night for comfort. This is a SINGLE-PERSON USE-ONLY fan and not for an entire room. RANDOM COLOR ONLY
